The DuraVent Concentric Vent System 3" Telescoping Adjustable Vent Pipe Length is a premium adjustable concentric vent pipe designed for safe and efficient venting of condensing and non-condensing gas appliances. Featuring a UL 1738-approved super-ferritic stainless steel inner wall, this telescoping vent section provides exceptional corrosion resistance and long-lasting performance. Its innovative twist-lock connection eliminates the need for clamps or mechanical fasteners, reducing installation time while creating a secure, gas-tight seal. With a 3-inch inner diameter and 5-inch outer diameter, this adjustable vent pipe allows both combustion air intake and exhaust through a single roof or wall penetration.

Engineered for installation flexibility, the DuraVent Telescoping Concentric Vent Pipe eliminates the need for field cutting by allowing precise length adjustments during installation. Integrated O-ring seals on both the inner wall and outer casing help prevent exhaust gas and combustion air leakage, while the built-in condensate management system minimizes standing moisture for dependable operation. Compatible with DuraVent Concentric Vent System components, this adjustable Galvalume vent pipe delivers professional-quality performance, reliable sealing, and efficient venting for high-efficiency gas furnaces, boilers, and water heaters.
